few years back, when we first downloaded google chrome too our dell deskptop, it crashed ALOT. took me some searching, and i found a answer online.
turns out, firefox and chrome in the same pc werent happy together they said.
im no pc expert, but as soon as i removed firefox files and program, and restarted the desktop, chrome hasnt crashed since.
like i said, im no pc guru, just found some people on cnet with same issue.
if firefox is working good and you like it, stay with it.
personally, chrome is more stable for what our family uses it for and is easy too work in incognito mode for privacy control.
good luck with your crashing issue!
